Medical device manufacturing takes place in cleanroom environments with strict requirements for atmospheric control. Depending on the production processes being undertaken, it can be the case that standard heating, ventilating and air conditioning equipment cannot provide the precise conditions necessary to turn a product design into a manufacturing reality.

By researching different environmental conditions and then maintaining them consistently at the optimum level during manufacturing Condair's helped manufacturers improve yields on products such as stents, sutures, blood glucose sensors and medical dressings.

Humidity is controlled in these environments for several reasons. It can be because the materials being processed are moisture sensitive and any change in their moisture content intrinsically changes their composition. This can be a dimensional change, a chemical imbalance or simply a drying of an aqueous based element.

Humidifiers can be used to eliminate static and to suppress dust and airborne particles. Humidification is also used as an activating agent. For instance, ethylene oxide can be used as a sterilising agent but only becomes active at 70%RH or above.
